Step 10
If you will set Path Trace Mode to Manual in Step 11, enter the string that the drop port should expect
to receive in the New Expected String field. This string must match the New Transmit String entered for
the source port in Step 5. (When you click Apply in Step 12, this string becomes the Current Expected
String.)

6.8 Cross-Connect Card Capacities
The ONS 15454 XC, XCVT, and XC10G cards perform port-to-port time-division multiplexing (TDM).
•
XCs perform STS switching
•
XCVTs and XC10Gs perform STS and VT1.5 switching
XCs and XCVTs have capacity to terminate 288 STSs, or 144 STS cross-connections (each STS
cross-connection uses two STS ports on the cross-connect card STS matrix). XC10Gs have capacity for
1152 STSs, or 576 STS cross-connections.
